Information reproducing system including a master and a slave system

Abstract

Two reproducing systems are provided for reproducing CDs respectively. Each port is provided in each recording system for connecting the reproducing systems by an external cord. A switch circuit is provided in the port and arranged such that an output level is changed by connecting the external cord. A system controller is provided in each reproducing system and responsive to the change of the output level for designating one of the reproducing systems as a master system, and for designating the other reproducing system as a slave system.

What is claimed is:  
     
       1. A system for reproducing information recorded on a recording medium comprising: 
       at least two reproducing systems, each of the reproducing systems having an automatic changer which comprises a storage configured to store a plurality of recording mediums and a pickup;  
       port means provided in each of the reproducing systems for connecting the reproducing systems by an external cord;  
       switch means provided in the port means, the switch means being arranged such that an output level is changed by connecting the external cord; and  
       control means provided in each reproducing system and responsive to the change of the output level for designating one of the reproducing systems as a master system, and for designating the other reproducing system as a slave system.  
     
     
       2. The system according to  claim 1  wherein the master system has an input port for receiving an information signal read at the slave system. 
     
     
       3. The system according to  claim 1  wherein each of the master system and the slave system has a maximum storing number N, and n slaves (M1 - - - Mn) are provided, a storing position in the slave Mn is expressed as N×n+1˜N×(n+1). 
     
     
       4. The system according to  claim 1  wherein the control means is provided for commanding the slave system to reproduce a desired recording medium when the desired recording medium is stored in the slave system. 
     
     
       5. The system according to  claim 2  wherein only the master system is connected an information emitting device, whereby the information signal is reproduced from the information emitting device. 
     
     
       6. A system for reproducing information recorded on a recording medium comprising: 
       at least two reproducing systems, each of the reproducing systems having an automatic changer which comprises a storage configured to store a plurality of recording mediums and a pickup;  
       ports provided in each of the reproducing systems for connecting the reproducing systems by an external cord;  
       switch circuits provided in the ports, the switch circuits being arranged such that an output level is changed by connecting the external cord; and  
       a system controller, provided in each reproducing system and responsive to the change of the output level for designating one of the reproducing systems as a master system, and for designating the other reproducing system as a slave system.  
     
     
       7. The system according to  claim 6 , wherein the master system has an input port for receiving an information signal read at the slave system. 
     
     
       8. The system according to  claim 6 , wherein each of the master system and the slave system has a maximum storing number N, and n slaves (M1 - - - Mn) are provided, a storing position in the slave Mn is expressed as N×n+1˜N×(n+1). 
     
     
       9. The system according to  claim 6 , wherein the system controller is provided for commanding the slave system to reproduce a desired recording medium when the desired recording medium is stored in the slave medium. 
     
     
       10. The system according to  claim 7 , wherein only the master system is connected with an information emitting device, whereby the information signal is reproduced from the information emitting device. 
     
     
       11. A system for reproducing information recorded on a recording medium comprising: 
       at least two reproducing systems, at least one of which has a storage storing a recording medium and a pickup;  
       ports provided in each of the reproducing systems for connecting the reproducing systems by an external cord;  
       switch circuits provided in the ports, the switch circuits being arranged such that an output level is changed by connecting the external cord;  
       a system controller provided in each reproducing system and responsive to the change of the output level for designating one of the reproducing systems as a master, and for designating the other reproducing system as a slave system.
